escapechar

Return the current escape character or \0 if it is undefined.
The escape character is retrieved from the count register
\escapechar.
This is a convenience method.

The Count Parameter \escapechar

The count register \escapechar contains code point of the
escape character. This character is used whenever an control sequence
is about to be printed and it has to be prefixed by the escape character.

If the value is less than zero then the escape character is assumed to
be undefined. In this case the control sequence is not prefixed by any
character.

Note that the escape character does not need to be in sync with the
definition of the category codes. In fact they are independent. Usually
they should coincide, but some interesting effects can be achieved with
controlled disagreement.

getLanguage

Getter for the hyphenation record for a given language. The language is
used to find the hyphenation table. If the language is not known an
attempt is made to create it. Otherwise the default hyphenation table is
returned.

setBox

Setter for the box
register in the current group. Count registers are named, either with a
number or an arbitrary string. The numbered registers where limited to
256 in TeX. This restriction does no longer hold for
ExTeX.

Parameters:

name - the name or the number of the register

value - the new value of the register

global - the indicator for the scope; true means all
groups; otherwise the current group is affected only

setMagnification

Setter for the magnification. The magnification is a global value which
can be assigned at most once. It contains the magnification factor in
per mille. The default value is 1000. It can only take positive numbers
as values. A maximal value can be enforced by an implementation.

Parameters:

mag - the new magnification factor

lock - lock the new value. Thus it can not be alterd afterwards.

Throws:

HelpingException - in case that the magnification factor is
not in the allowed range or that the magnification has been
set to a different value earlier.
